Management of hereditary angioedema should include fresh frozen plasma containing C1 inhibitor (C1-INH), whenever possible; if C1-INH-containing plasma is unavailable, fresh frozen plasma can be used instead. Do not give neomycin to patients with suspected cellulitis; the drug may promote antibiotic resistance in Staphylococcus aureus, a pathogen often associated with this condition. Whenever a patient presents with erythematous skin lesions and a recent history of receiving penicillin or a cephalosporin antibiotic, a sulfa derivative, or an anticonvulsant, the suspected medication should be stopped until Stevens-Johnson syndrome is ruled out.

Papillary Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.

The papillary layer is made of loose, areolar connective tissue, which means the collagen and...
